On some classes of formulas in S5 which are pre-complete relative to existential expressibility
Existential expressibility for all $k$-valued functions was proposed by A.~V. Kuz\-ne\-tsov and later was investigated in more details by S.~S.~Mar\-chen\-kov. In the present paper, we consider existential expressibility in the case of formulas defined by a logical calculus and find out some conditi...
